APPARATUS FOR PURlFYlNG FEED-WATER.

SPECIFICATION forming part of Letters Patent No. 390,927, dated October 9, 1888.

Application iiil"i Mn) Ill, 1885.

To aZZ whom it may concern.-

Be it known that l, \VAltltllN \Vnns'ri-ut, a citizen 0! the United States, residing in the city and county of Philadelphia, State oi"l.ennsylvania, have invented a new and useful improvement in Apparatus for Purifying Feed- Water, which improvement is fully set forth in the following specification and accompanying drawings.

Myinvention relates to improvements in apparatus for purifying water, and is especially designed aslan improvement upon similar apparatus for which I. have made applications for Letters Patent March 29, 188s, Serial r 0. 268,859, and May 3, 18.98, Serial No. 27am 1..

The object of the present invention is to improve the construction of the before-mentioned apparatus, and provide one which shall be simple in construction, thoroughly efficient in operation, and inexpensive ol' product-ion.

The invention consists of a water-purifier comprising an outer vessel or shell havinglocated therein a vaporizing and purifying chamber, a sediment well or receptacle, and a condensing-chamber;further, in an outer casing or shell eoutaininga vaporizing and purifying chamber, a sediment well or receptacle, a con densing-chamber,adelivery-pipecomnumicating with the vaporizing or purifying and con- (lensing chamber, water and steam supply pipes, and an overilow pipe, all arranged as shown; and, finally, the invention consists in the details of construction and adaptation olf parts for service, as lnn-einal't-er described and specifically claimed.

Figure .1. represents a vertical longitudinal sectional view oian apparatus for purifying water embodying my invention. Fig. 2 represents a perspective view of the shell-walled case which provides the purifying and vaporizing chamber.

Similar numerals of reference indicate corresponding parts in the two ligurcs.

,lteierring to the drawings, the numeral 1 represents the outer casing orshcll of my apparatus, provided with the cover or lid 2, which is secured in place by means of the clamping device This shell is divided into three compartments, which are designated the vaporizing or purifying chamber 4, the condensing-chamber 6-, and the sediment well or receptacle 6. The sediment-well is provided Serial No. 3713-14. (No Hi di-i.)

I with the discharge-pipes 7 and 7 the former being provided with a cock, 7', the puril'ying-chamber is provided with the stcam-supply pipe S, having abraneh pipe, 8, provided with a safety-valve, 8", and leading thcrcfrom to the discharge-pipe 7, and said chamber is also provided with an overflow-pipe, 3*, leading also to the discharge-pure '7.

9 represents the delivery-pipe, which leads fgom the condcnsirig-chamber to a pump.

The purilyiugchamber is formed by means of the three-walled case 10, or the trout partition extending entirely across the chamber, the side inner walls could be dispensed with; but the latter are preferred on account of enlarging the condcnsingcompartment, which extends down into the sediment-well, the purpose of which will presentlyappear.

in the purilying-chambcare located a serics of perforated trays or plates, ii, and the highest plate con'inmnicatcs with a' distribut ing device, l2.

In the sediment -well are arranged a series of inclined plates, 13, which may, if desired, be perforated. These plates are inclined, in order to insure a perfect precipitation of the sediment and also to prevent agitation of the same.

i l represents the pipe for supplying water to the purilicr, which is provided with a cock or valve, 1.), and this pipe enters the condens ing-chamber at the top of the shell and supplies the water through the pipes .16 in the condensing-ehambcr to the distributing device 12. The supply-pipe is show u as entering the top of the condensing-chambcr in. this case; but there is no objection to having it enter in any other part of the chamber, and i do not limit myself to the place of entrance.

Above the purilying-chamber and below the pipes 16 in the condensirig-chamber is arranged a series of plates or steps, 17, forming an inclined passage to allow vapors to pass freely from the vaporizingchamber into the condensirig-compartment, but to prevent the vapors when in a liquid form from returning again into the vaporizingchamber.

. I do not wish to be limited to this peculiar style of plate, as any arrangement oi gnttered sheets would answer the purpose as well.

The shell or casing is provided with an air outlet or discharge pipe, 18, by means of 'ren1oviug grease or oil which accumulates.

' in case water should baclcand enter the delivery-pipe before first passing through the cry-pipe.

which air is prevented from accumulating in the condensing-cha1nbcr, and the air is drawn outby any suitable means. A branch pipe, 19, leads from the discharge-pipe, and awatergagc, 20, communicates" with the dischargepipe, the purpose oi said gage being to ascertain the amount of water in the purifying chamber. a v

The object of cheek-valves being placed in the overflow-pipes asfal' down as possible below the level of the water in the purifier is that a vacuum may be maintained in the purifier, even whcnthe pnm p which is connected to the delivery is running too slowly to carry all ofihe water away as quickly as it is purifled. The amount of vacuum would be in proportion to the distance the check-valve would be placed in the overflow-pipe below the level of water in the purifier.

The operation is as follows: Water and steam are admitted by means of the water and steam. supply pipes. The waterpasses through the pipes and the distributing device, and from thence to the perforated trays or plates. The steam, passing through said water in its passage over and through the trays, vaporizes the water, removing the impurities therefrom, .which impurities'l'all upon the inclined plates in the scdimcnt-wcll and are precipitated into said well, being prevented from agitation by said plates. The pure water remains above the impurities and flows out through the deliverypipo. flhc grease and light impurities are prevented from passing out with the pure water, on account of the wall being always be low the level of the delivery and preventing them from getting past.

The heated vapors from the steam rising above the trays comes in contact with the cold-water-supply pipes, and is thereby con doused and falls in a shower upon theincline'l passage or steps l7 .and is directed thereby to the delivery-pipe, and the air which rises to the top of the condensing chamber escapes through the air-outlet pipe.

In case too great an amountoi water-should accumulate in the purifyingchzrmbcr it will pass out through the everli'iw-pipe to the dis charge-pipe.

By having the three-walled partition forming the purifyiug-chamber extending downward into the sediment-well below the level of the water the vapors cannot pass out of the vaporizing-chaniber, and then coiningin con tact with the condcnsing-surface,consequently becoming liquefied before entering the deliv- The peculiar arrangement of the inclined plates in the sediment-well causes thejscdimerit to be more rapidly precipitatcrh'and also prevents agitation of said impurities if lhe-dischargc-pipe 7 preferably le'at the bottom of the inclined plate n'carest 'the dclivciypipc, and is especially adapted for steam pipe it will be directed into the branch pipe which leads therefrom to the dischargepipe, and this branch pipe has a valve which is opened by the pressure, weight, or gravity of the water, but which is retained normally in a closed position. The branch pipe thus serves to prevent water which may enter the steamsnpply pipe from reaching the engine. Having thus described my invention, what I claim as new, and desire to secure by 'lk'tters Patent, is-- l. A water purifying and vaporizing apparatus consisting of a purifying-chamber with a steam-inlet pipe and a water outlet-pipe, a
